An alert will sound across the country on July 27. Advocates worry it will place some women at risk

On July 27, a loud alarm will blare from every mobile phone in Australia. It’s part of testing for the new AusAlert system, which will inform people about emergencies in their area, including natural disasters, public safety threats and bio-security incidents. But there are concerns the alert could put victim-survivors of family and domestic violence with hidden phones at risk.
